musl/include/sys, branch v1.2.2 musl - an implementation of the standard library for Linux-based systems sys/fanotify.h: add new FAN_* macros from linux v5.9 2020-11-29T05:54:36+00:00 Szabolcs Nagy nsz@port70.net 2020-10-25T16:25:34+00:00 d078f836578986d97728b71ee2a7fd33233fbd5d Update fanotify.h, see linux commit 929943b38daf817f2e6d303ea04401651fc3bc05 fanotify: add support for FAN_REPORT_NAME linux commit 83b7a59896dd24015a34b7f00027f0ff3747972f fanotify: add basic support for FAN_REPORT_DIR_FID linux commit 08b95c338e0c5a96e47f4ca314ea1e7580ecb5d7 fanotify: remove event FAN_DIR_MODIFY FAN_DIR_MODIFY that was new in v5.7 is now removed from linux uapi, but kept in musl, so we don't break api, linux cannot reuse the value anyway. 
Update fanotify.h, see

  fanotify: remove event FAN_DIR_MODIFY

FAN_DIR_MODIFY that was new in v5.7 is now removed from linux uapi,
but kept in musl, so we don't break api, linux cannot reuse the
value anyway.

FDPIC_FUNCPTRS was also missing its corresponding PER_LINUX_FDPIC value.

fix regression with applications that expect struct winsize in ioctl.h 2020-08-30T20:47:40+00:00 Rich Felker dalias@aerifal.cx 2020-08-30T20:47:40+00:00 1ccc804e1345c6e59294f561ac43c3e55ccea1e4 putting the (simple) definition in alltypes.h seems like the best solution here. making sys/ioctl.h implicitly include termios.h is probably excess namespace pollution.

add tcgetwinsize and tcsetwinsize functions, move struct winsize 2020-08-25T01:31:18+00:00 Rich Felker dalias@aerifal.cx 2020-08-24T16:29:30+00:00 4d5786544bb52c62fc1ae84d91684ef2268afa05 these have been adopted for future issue of POSIX as the outcome of Austin Group issue 1151, and are simply functions performing the roles of the historical ioctls. since struct winsize is being standardized along with them, its definition is moved to the appropriate header. there is some chance this will break source files that expect struct winsize to be defined by sys/ioctl.h without including termios.h. if this happens, further changes will be needed to have sys/ioctl.h expose it too.
